she belied with false compare -shakespeare

could you help me to translate this line
and yet by heaven I think my love is rare
as any she belied with false compare
y aunque creo que mi amor es excepcional
como alguno........con falsa comparacion
In this sonnet shakespeare describe the black lady ,and she is not beauty , according his time

"as any she belied with false compare" = "as any woman people lie about by making false comparisons"

In Shakespeare, 'she' is sometimes used to mean "a woman". (For example, in Twelfth Night, there's a line about someone being "the cruelest she alive".)

He's saying that his mistress is as rare as those other women people write untruthful poems about (where they say their mistresses eyes are like the sun and so on). This poem is a parody of an earlier one that makes all of those comparisons.
